It comes with Lotus built into the ROM. In fact, the ability to run Lotus 123 was the genesis of the HP plamtops. One of my gripes about Lotus 123 is that it excelled (pun intended) at losing your work, as it did not ask you to save the file when you quit -- "/Q" would quit the program whether or not you had unsaved work. Bob?? PS. Re the "what calcularor to get" thread, you can get an HP LX200 and run any of a number of MS-DOS HP calculator emulators on it.

old clocks

hp calculators

by tshoppa＠wmata.com

It's still not too hard to find a HP-25. Retrofit the rechargeables and you're set. But IMHO the true sweet spot is a HP-15C or HP-11C. A set of batteries will last for years. I am not a huge fan of bells-and-whistles features.

Free! HP Netserver LX Server P-Pro Parts

by mikelee＠tdh.com

Not all that "classic" but figured I'd make the offer in case someone needed pieces or parts. Located near the Chicago area, willing to ship parts and I highly doubt anyone would want the whole thing. You however might want HP SCA drive trays (also works in the other HP storage stuff the same age), scsi/sca backplanes (6 drive slots per side, actually quite nice drive cages if you wanted to do something with that), power supplies, proc or mem boards or anything else. It's a mini-fridge sized multi-proc Pentium Pro server with 12 half height drive bays, 3 power supplies, etc. One last offer for parts from this beast before I part it out and scrap it. I'm keeping the basics memory, procs and drives, but I can be convinced to part with those as well if you have a need. Nice machine for its time, but the 1kW/hr power use and physical size is convincing me to get rid of it. Once again, located in the Chicago area. Crossposted, so first come first serve and closer the better. Mike

In fact Googlebot is regularly scanning all my ftp sites quite regularly. But I would not classify as usefully return search information. There are several other bots out there (some of them russian, one of them may be mmnt) scanning ftp sites. Remember when archie did all this? (Or at least, tried to do all this.)

old clocks

by Arno_1983＠gmx.de

Oh well, another post that reminds me of all that tinkering I'd like to do but can't due to lack of time right now. There is a broken Siemens "Hauptuhr" (master clock) HU 10 in one of ?y banana boxes from hell, which formerly did its duty in a school in my district. This is more modern (I'd say 70s if not 80s vintage) unit with a lead-acid battery for backup and a discrete electrical second (or maybe half-second) oscillator driving the "seconds" part of the mechanical work, which in turn actuates a contact to generate "minute" pulses for both the minutes/hours hands of the local dial and the slave clocks. It seems that just the primary oscillator or maybe the seconds actuator is broken, as manually generating pulses via the Set button does advance the hands as expected. What's more, the device also comprises a loop of, IIRC, 5-level punched tape in a box with, I think, one "character" position for every five minutes in either 24 hours or even seven days, which would usually probably be used to ring a bell for signalling the breaks at the desired times (on schooldays), but could of course also accomodate other functions. I also do have a kind of slave clock, but not the usual hands-and-dial variety - mine is a digital one which looks like it was from some kind of larger office and works by means of plastic sheets printed with numbers and arranged in a horizontal drum, which flip downward, one per minute, at the actuation of a magnet. Besides hours and minutes, this thing also has a whole calendar with day-of-week, day-of-month and month display derived from this movement, but I've not yet investigated how it deals with the different lengths of the months, i.e. whether it will need manual intervention every two months or just once a year (apart from going into/leaving DST, of course). Unfortunately some greedy, egoistic creature has pilfered some of the flip sheets, so these will have to be recreated using some kind of plastic stock and painted to match the figure patterns of the rest.

Supposedly from their Fortran manual: "The primary purpose of the Data statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable Pi can be given that value with a Data statement and used instead of the longer form of the constant. This also simplifies modifying the program, should the value of pi change." mike

> start by undoing a lot of what they had previously been taught, such as > that PI was EXACTLY 22/7 ! (half a century ago, in elementary school, I > got into "big trouble" for telling a teacher that PI was NOT 22/7 !) Aarrghh!! Is that what they teach in American schools?? That is *evil*. My mother once had a teacher who when his pupils were bad, told them to behave, otherwise he would teach them wrong. In his opinion that was the worst punishment he could think of. I am absoutely sure that over here everybody is taught, and always has been, the difference between natural, real, rational and irrational numbers, and that pi is an irrational number which can be approximated by 22/7. The Swedish school system may have very serious problems, but hearing this kind of thing makes me very, very grateful that my kids haven't grown up in the USA. /Jonas

Sperry 5000/Arete' 1200 Unix Mini

by silent700＠gmail.com

We have had a successful mission with the Sperry minicomputer pickup. We dodged the rain showers and successfully loaded a ~5' rack and two Fujitsu tape drives into two vehicles, then broke for dinner. Here are pics from today, with more to come of internal bits: https://picasaweb.google.com/102190732096693814506/Sperry1200Pickup# The machine appears to be an Arete' 1200, although badged as a Sperry on the front. Research suggests it is equivalent to a Sperry 5000/80 machine. It is a Motorola 68000-based UNIX minicomputer. This one appears to have two CPU boards (each with a 68020 processor,) a few RAM boards for a total of 30MB of RAM, and is missing all of its storage. The drives it used seem to be SMD interfaced but we're not sure what it had originally as there are external and internal connectors. Two Fujitsu 9-track tape drives, model M2444AC, came with the Sperry and we assume they were used with it, too. They are heavy! Here is some information on the Sperry 5000 line. Truly a unique machine! http://www.porterdavis.org/computing/sperry.html -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

I don't have any problem with X11 as long as you run a standards-compliant web browser in an X11 window :-). Or an xterm. There's very little today I do in X11 that isn't in a web browser or an xterm, don't you know :-) X11 just does not satisfy me as a way to define a high-information-content user interface. It's certainly capable of delivering a high-information-content user interface but it doesn't define it. The web by itself isn't too fancy but couple with Javascript, AJAX, SVG and other high-information-value media of interchange, and boy is it fun to work in! With just a little care, apps scale up enormously and deploy with so little effort on my part. You might note I left out many common web standards as being high information value. Tim.

Useful languages on UNIX that are not C - was Re: C, trivia - was Re: Dennis Ritchie has died

by ken＠seefried.com

One of the many potentially great things that died when DEC did was Modula-3, a language with huge promise (and one that didn't jump the shark with Wirth (see: Oberon)). There's a small community keeping it alive, and it's design is still influential (the creator of Python cites it as a primary influence). Perhaps it's time to give it another look. Whenever these sorts of "what should the language look like..." debates come up, as often as not I think "sounds like Modula-3".
